1) An alternate proposal for the Trademark Clearinghouse (TMCH) is presented that uses public key infrastructure (PKI) instead of obscure sunrise codes used in ICANN's model.
2) Issues with ICANN's sunrise and claims models are discussed, including complexity for trademark owners and inability of registries to access trademark information.
3) The alternate proposal aims to reduce complexity, increase security and flexibility, and provide registries access to trademark information submitted by applicants.
